Is Reverse Phone Lookup Legal in Maryland?
Yes. Maryland does not restrict the personal use of reverse phone lookup services, and its privacy law - which took effect October 1, 2025 - is considered one of the strongest in the country. The Fair Credit Reporting Act (FCRA) prohibits using lookup results for employment, tenant, or credit decisions in every state. Maryland's MODPA goes well beyond the federal baseline.
Why Maryland Residents Have Stronger Protections Than Most
The Maryland Online Data Privacy Act (MODPA, Md. Code, Com. Law § 14-4601 et seq., enacted May 9, 2024) took effect October 1, 2025. Note that it does not apply retroactively to personal data processed before April 1, 2026. What makes MODPA stand out is its data minimization requirement: businesses may not collect or process personal data beyond what is "reasonably necessary and proportionate" to deliver the requested service (MODPA § 14-4604(a)). This is a stricter standard than most states, which only require an opt-out option after collection has already occurred. Maryland also covers nonprofits broadly - only a narrow exception for organizations processing data solely to assist law enforcement or first responders is carved out (§ 14-4602(b)).
Residents have a 45-day response window for access, correction, deletion, and portability requests. There is no small-business exemption.
